    The best quote from this cesspit, although there may be many more goodies that I missed (you can bet I have not read everything).

    I am surprised this has gone on and on. This site is supposed to...

    If really for long term storage, vaseline seems to be unaffected by humidity, and does a good job of rust prevention.

    It's not power, but "apparent power", or VA. Current at a bad power factor, same thing as a considerable lagging phase. Amounts to much less actual "power", the power is the VA x cosine of phase...

    Well, then it is the speed readout from connection 14 maybe.... it would surprise me if that was a single wire, though.

    What DOES that wire connect to continuity-wise?

    Looks as if the third wire is just a ground. Apparently a green/yellow wire, right? So the others are + and - and you know what to do with them.

    Your customer is likely assuming you will send the "stp" file to a CAM program and do the parts "on your CNC" (which it sounds like you may not have).

    If that is the case, and the parts are one of...

    The other way around this is to use a different type receptacle which does carry the current/voltage ratings needed.

    The receptacle need not be normally used for the application, so long as the...

    Power company 3 phase is quite stable in voltage. Powerco has to keep it in tight regulation, 10% high is max, and most want to keep it under 6% high. For you, maximum is 264VAC on 240VAC.

    Probably the static type, which for that company seems to be one involving a transformer and capacitors. Possibly the Steelman method?

    Anyhow, those may not produce the correct voltage unless...

    The transformers are drawing kVA at a lousy power factor, possibly as low as 0.1, because there is a lot of VA and likely not much wattage. It is the "magnetizing current" and since it is flowing...

  19. An old style metric micrometer, and an off brand metric micrometer (McGrath)

    The old style is really a clunky old style.

    It is metric, and actually seems to agree very well with my newer metric mics, at least for small measurements.

    The "fooling" is in the interpretation. The current is real and factual, actual electrons are flowing. Do not make the mistake of assuming the current is not real.
